次に、車両用ブレーキ液圧制御装置１０の動作を説明する。なお、ブレーキレバー１１から前輪ブレーキキャリパ１４までの第１系統と、ブレーキペダル２１から後輪ブレーキキャリパ２４までの第２系統とは、動作が同じであるため、第１系統のみを説明する。 Next, the operation of the vehicle brake fluid pressure control device 10 will be described. Since the first system from the brake lever 11 to the front wheel brake caliper 14 and the second system from the brake pedal 21 to the rear wheel brake caliper 24 have the same operation, only the first system will be described.

・ＡＢＳ非作動状態：前輪がロックする心配がないときは、制御装置３０で、第１ポンプ１７を停止し、第１入口制御弁１５を開き、第１出口制御弁１６を閉じる。この状態で、ブレーキレバー１１が制動側に操作されると、第１マスタシリンダ１２で液圧が高められ、この液圧が第１入口制御弁１５を介して前輪ブレーキキャリパ１４に伝えられる。 -ABS non-operational state: When there is no risk of locking the front wheels, the controller 30 stops the first pump 17, opens the first inlet control valve 15, and closes the first outlet control valve 16. When the brake lever 11 is operated to the braking side in this state, the hydraulic pressure is increased in the first master cylinder 12, and this hydraulic pressure is transmitted to the front wheel brake caliper 14 via the first inlet control valve 15.

・ＡＢＳ（減圧モード）：前輪がロックしそうになると、制御装置３０は、第１入口制御弁１５を閉じ、第１出口制御弁１６を開く。前輪ブレーキキャリパ１４内の液圧は、第１出口制御弁１６を介して第１リザーバ１３へ逃がされる。これで前輪ブレーキキャリパ１４のブレーキ液圧が減圧される。 -ABS (pressure reduction mode): When the front wheels are about to lock, the control device 30 closes the first inlet control valve 15 and opens the first outlet control valve 16. The hydraulic pressure in the front wheel brake caliper 14 is released to the first reservoir 13 via the first outlet control valve 16. As a result, the brake fluid pressure of the front wheel brake caliper 14 is reduced.

・ＡＢＳ（保持モード）：制御装置３０は、第１入口制御弁１５と第１出口制御弁１６を共に閉じる。これによって、前輪ブレーキキャリパ１４のブレーキ液圧が一定に保持される。 -ABS (holding mode): The control device 30 closes both the first inlet control valve 15 and the first outlet control valve 16. As a result, the brake fluid pressure of the front wheel brake caliper 14 is kept constant.

・ＡＢＳ（増圧モード）：ブレーキ液圧を増圧する際は、制御装置３０は、第１入口制御弁１５を開け、第１出口制御弁１６を閉じる。これによって、マスタシリンダ１２で発生された液圧が、前輪ブレーキキャリパ１４に伝えられる。これで前輪ブレーキキャリパ１４のブレーキ液圧が増圧される。 -ABS (pressure increase mode): When increasing the brake fluid pressure, the control device 30 opens the first inlet control valve 15 and closes the first outlet control valve 16. As a result, the hydraulic pressure generated in the master cylinder 12 is transmitted to the front wheel brake caliper 14. With this, the brake fluid pressure of the front wheel brake caliper 14 is increased.

図２に示されるように、基体４０に、第１入口制御弁としての電磁弁１５及び第１出口制御弁としての電磁弁１６が取付けられるとともに、第１リザーバ１３が内蔵され、ブレーキ液路Ａ１、Ｃ１などが設けられ、ブレーキ液路Ａ１とブレーキ液路Ｃ１との間に第１ポンプ１７が設けられている。 As shown in FIG. 2, a solenoid valve 15 as a first inlet control valve and a solenoid valve 16 as a first outlet control valve are attached to a base body 40, a first reservoir 13 is built in, and a brake fluid passage A1 is provided. , C1 and the like, and the first pump 17 is provided between the brake fluid passage A1 and the brake fluid passage C1.

電磁弁１５及び電磁弁１６は、軸方向の長さにおいて約半分程度が、基体４０から突出し、これらの突出部分が樹脂製部品３６に収納される。以下、樹脂製部品３６をハウジング３６と読み替える。電磁弁１５及び電磁弁１６は各々駆動用の電磁コイル３３を備えている。 About half of the solenoid valves 15 and 16 in the axial length project from the base body 40, and these projecting portions are housed in the resin component 36. Hereinafter, the resin component 36 will be read as the housing 36. The electromagnetic valves 15 and 16 each include an electromagnetic coil 33 for driving.

ハウジング３６は、表側（カバー３８側）および裏側（基体４０側）に開口部を有し制御基板９９を収納する周壁部８４を備えている。
ハウジング３６内に制御基板９９が配置されており、この制御基板９９と電磁コイル３３が端子９１で電気的に接続されている。The housing 36 includes a peripheral wall portion 84 having openings on the front side (cover 38 side) and the back side (base body 40 side) and housing the control board 99.
A control board 99 is arranged in the housing 36, and the control board 99 and the electromagnetic coil 33 are electrically connected by terminals 91.

図２の３ｃ部拡大図を図３（ｃ）に示す。
図３（ａ）に示されるように、ハウジング３６に備えるカバー３８は、カバー３８の外周に一方（ハウジング３６側）に突出する挿入凸部３８ａが形成され、この挿入凸部３８ａに樹脂を溜める溜まり溝３８ｂを備えているとともに、上下に延びる突起３８ｃを備えている。そして、基板収容部８５を囲う周壁部８４には、カバー３８を取付ける取付部３６ａが形成され、この取付部３６ａには挿入凸部３８ａが差し込まれると共に接着剤３６ｂが充填される上部溝３６ｃが形成されている。An enlarged view of section 3c of FIG. 2 is shown in FIG.
As shown in FIG. 3A, a cover 38 provided in the housing 36 has an insertion protrusion 38a formed on the outer periphery of the cover 38 and protruding toward one side (housing 36 side), and the resin is collected in the insertion protrusion 38a. It has a reservoir groove 38b and a protrusion 38c extending vertically. A mounting portion 36a for mounting the cover 38 is formed on the peripheral wall portion 84 surrounding the substrate housing portion 85, and the mounting convex portion 38a is inserted into the mounting portion 36a and the upper groove 36c filled with the adhesive 36b is formed. Has been formed.

カバー３８は、挿入凸部３８ａより外側に、ハウジング３６側の取付部３６ａに当たる当接部３９を備えている。 The cover 38 is provided with an abutting portion 39, which abuts the mounting portion 36a on the housing 36 side, outside the insertion convex portion 38a.

挿入凸部３８ａに突起３８ｃを設け、カバー３８の取付時に突起３８ｃが上部溝３６ｃの内面に摺接するようにした。カバー３８が水平方向に移動しようとすると、突起３８ｃが上部溝３６ｃの内面に当たっているため、水平方向の移動が防止される。結果、カバー３８をハウジング３６に取り付ける際のがたつきを防ぐことができる。
挿入凸部３８ａの下端部にテーパー面３８ｆを設けることにより、挿入凸部３８ａの下端を先尖り形状にする。この形状であれば、挿入凸部３８ａが、円滑に溝３６ｃに収容されると共に、接着剤３６ｂを円滑に押し分ける。A protrusion 38c is provided on the insertion convex portion 38a so that the protrusion 38c is brought into sliding contact with the inner surface of the upper groove 36c when the cover 38 is attached. When the cover 38 tries to move in the horizontal direction, the protrusion 38c abuts the inner surface of the upper groove 36c, so that the cover 38 is prevented from moving in the horizontal direction. As a result, rattling at the time of attaching the cover 38 to the housing 36 can be prevented.
By providing the tapered surface 38f at the lower end portion of the insertion convex portion 38a, the lower end of the insertion convex portion 38a has a pointed shape. With this shape, the insertion convex portion 38a is smoothly accommodated in the groove 36c, and the adhesive 36b is pushed smoothly.

上部溝３６ｃに接着剤３６ｂを置き、カバー３８を下げると、上部溝３６ｃに挿入凸部３８ａが進入する。図３（ｂ）に示されるように、接着剤３６ｂは挿入凸部３８ａで押され、一部が周壁部８４外や周壁部８４内へ向かう。
図３（ｃ）に示されるように、接着剤３６ｂは、溜まり溝３８ｂに流れるため、ハウジング３６の外面に溢れることがなくなる。When the adhesive 36b is placed in the upper groove 36c and the cover 38 is lowered, the insertion protrusion 38a enters the upper groove 36c. As shown in FIG. 3B, the adhesive 36b is pushed by the insertion protrusion 38a, and a part of the adhesive 36b goes to the outside of the peripheral wall portion 84 or the inside of the peripheral wall portion 84.
As shown in FIG. 3C, since the adhesive 36b flows into the reservoir groove 38b, it does not overflow onto the outer surface of the housing 36.

なお、第２溜まり溝３６ｄを、ハウジング３６側に設けることで、溜まり溝３８ｂ、３６ｄの断面積を拡大することは望ましいことである。 It should be noted that it is desirable to increase the cross-sectional area of the reservoir grooves 38b and 36d by providing the second reservoir groove 36d on the housing 36 side.

次に、変更例を、図４及び図５に基づいて説明する。
図４に示されるように、ハウジング３６の取付部３６ａにおいて、上部溝３６ｃに溜まり溝３８ｂを形成しても良い。その他の構成は、図３と同じであるため、図３の符号を流用し、詳細な説明は省略する。
図５に示されるように、カバー３８側に溜まり溝３８ｂを形成しても良い。その他の構成は、図３と同じであるため、図３の符号を流用し、詳細な説明は省略する。Next, a modified example will be described based on FIGS. 4 and 5.
As shown in FIG. 4, in the mounting portion 36a of the housing 36, a reservoir groove 38b may be formed in the upper groove 36c. Since other configurations are the same as those in FIG. 3, the reference numerals in FIG.
As shown in FIG. 5, a reservoir groove 38b may be formed on the cover 38 side. Since other configurations are the same as those in FIG. 3, the reference numerals in FIG.

このように、溜まり溝３８ｂは、ハウジング３６側に設けることや、カバー３８側に設けることや、ハウジング３６とカバー３８とに跨って設けることができる。
すなわち、溜まり溝３８ｂは、ハウジング３６の取付部３６ａに備える上部溝３６ｃに設けることや、カバー３８の挿入凸部３８ａと当接部３９の間に設けることができる。
溜まり溝３８ｂは、カバー３８の挿入凸部３８ａと当接部３９の間、又は取付部３６ａの上部溝３６ｃの少なくとも一方に備えられる。In this way, the reservoir groove 38b can be provided on the housing 36 side, on the cover 38 side, or across the housing 36 and the cover 38.
That is, the reservoir groove 38b can be provided in the upper groove 36c provided in the mounting portion 36a of the housing 36, or can be provided between the insertion convex portion 38a and the contact portion 39 of the cover 38.
The reservoir groove 38b is provided between the insertion convex portion 38a of the cover 38 and the contact portion 39, or at least one of the upper groove 36c of the mounting portion 36a.

図６に示されるように、ハウジング３６からカバー３８側へ突出部３６ｅが突出形成されている。この突出部３６ｅは、カバー３８の挿入凸部３８ａを収容する上部溝３６ｃが形成されている取付部３６ａに設けられている。この突出部３６ｅは、カバー３８を固定（正確には接着固定する際の仮固定）する。以下、突出部３６ｅを固定部３６ｅと言う。
この固定部３６ｅは、取付部３６ａからカバー３８側へ延びる門型部材である。固定部３６ｅの角穴３６ｆに、カバー３８に設けた突起３８ｅが掛かるため固定（仮固定）される。As shown in FIG. 6, a protrusion 36e is formed so as to protrude from the housing 36 toward the cover 38. The protruding portion 36e is provided on the mounting portion 36a in which the upper groove 36c for accommodating the insertion convex portion 38a of the cover 38 is formed. The protruding portion 36e fixes the cover 38 (to be precise, temporary fixing when performing adhesive fixing). Hereinafter, the protruding portion 36e is referred to as the fixed portion 36e.
The fixing portion 36e is a gate-shaped member extending from the mounting portion 36a toward the cover 38 side. Since the projection 38e provided on the cover 38 is engaged with the square hole 36f of the fixing portion 36e, the fixing portion 36e is fixed (temporarily fixed).

カバー３８は、所定ピッチで複数の突起３８ｃを備えており、これらの突起３８ｃが上部溝３６ｃの外側壁面に接するため、カバー３８は水平移動や、回転することなく、ハウジング３６に取付けられる。
尚、実施例では、突起３８ｃはカバー３８の外面に設けたが、突起３８ｃをカバー３８の内面に設けてもよい。この場合は、突起３８ｃは上部溝３６ｃの内側壁面に接する。The cover 38 is provided with a plurality of protrusions 38c at a predetermined pitch, and since these protrusions 38c contact the outer wall surface of the upper groove 36c, the cover 38 is attached to the housing 36 without horizontal movement or rotation.
Although the projection 38c is provided on the outer surface of the cover 38 in the embodiment, the projection 38c may be provided on the inner surface of the cover 38. In this case, the protrusion 38c contacts the inner wall surface of the upper groove 36c.

図２の７ｂ部拡大図が図７（ｂ）で示され、図７（ｂ）の分解図が図７（ａ）に示される。
図７（ａ）に示されるように、ハウジング３６の周壁部８４は、基体４０に当接するフランジ９２を備え、このフランジ９２は、周壁部８４より外側に張り出しており、基体４０側の面に接着剤９２ａを溜める下部溝９２ｂを有している。そして、下部溝９２ｂの底面９２ｃが粗面９２ｄとされている。An enlarged view of portion 7b in FIG. 2 is shown in FIG. 7(b), and an exploded view of FIG. 7(b) is shown in FIG. 7(a).
As shown in FIG. 7A, the peripheral wall portion 84 of the housing 36 is provided with a flange 92 that abuts the base body 40. The flange 92 projects outward from the peripheral wall portion 84 and is provided on the surface of the base body 40 side. It has a lower groove 92b for accumulating the adhesive 92a. The bottom surface 92c of the lower groove 92b is a rough surface 92d.

接着剤９２ａが下部溝９２ｂに収容されるようにしつつ、基体４０にハウジング３６を当てる。
すると、図７（ｂ）に示されるように、接着剤９２ａは、アンカー効果により粗面９２ｄに接着され、基体４０にハウジング３６が強固に接着され、界面剥離を防止できる。The housing 36 is applied to the base 40 while the adhesive 92a is accommodated in the lower groove 92b.
Then, as shown in FIG. 7B, the adhesive 92a is adhered to the rough surface 92d by the anchor effect, the housing 36 is firmly adhered to the base 40, and the interface separation can be prevented.

また、図７（ｂ）において、フランジ９２の基体４０側の面は、下部溝９２ｂで外側面９２ｅと内側面９２ｆとに区分されているが、内側面９２ｆと基体４０との間に微小な隙間９２ｇを設けるようにした。
接着剤９２ａの余剰分が、微小な隙間９２ｇに流入するため、接着剤９２ａがハウジング３６内部へ侵入する心配が無くなる。Further, in FIG. 7B, the surface of the flange 92 on the side of the base body 40 is divided into the outer surface 92e and the inner side surface 92f by the lower groove 92b, but a small gap is formed between the inner side surface 92f and the base body 40. A gap 92g is provided.
Since the surplus amount of the adhesive 92a flows into the minute gap 92g, there is no concern that the adhesive 92a will enter the inside of the housing 36.
